STEREOTYPEBBLOCK.

SPECIPICATON forming part of Letters Patent No. 340,104, dated April 20, 1886. Application filed January 23, 1886. Serial No. 189,449. (No model.)

To @ZZ whom, it may concern.:

Beit known that we, GEORGE DEMON, of

Cranford, Union county, N ew Jersey, and ELIAS S. PEETS, of the city, county, and State of New York, have invented Improvements in StereotypeBlocks for Holding Stereotype- Plates in Position for Printing; and we do declare the following to be a full,clear, and correct description of the same, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, in which like parts are designated by the same letters of reference.

Figure l is a view of our invention, the stereotype-plate being shown removed from its position upon the blocks. Fig. 2 is a view of the invention, the stereotype plate being shown in position upon the blocks.

The nature of the present invention relates to improvements in stereotype-plates and the blocks or furniture used to support them, as more fully set forth, and will be found to consist in improvements on the invention in this class for which Letters Patent (now owned by us) were granted Marshall J'. Hughes, February 25, 1873, the object of the invention being to construct a stereotype-plate and its supportingblocks or furniture so that when locked up in the chase and placed on the bed of the press for printing purposes it will be held more securely in position, and the liabiiity to work loose will be greatly diminished.

To enable those skilled in the art to make and use our invention we will describe the same.

A shows the plate employed by us, which may be a stereotype, an electrotype, or one formed from Celluloid or like material. This plate A is provided upon its back or under side with the flanges B B2,placed about midway between t-he center and outer edges of the plate A. VThe blocks or furniture forsupporting the plate A, when placed in a chase and locked up, consist of a central block, C, made in length to correspond with the distance between the iianges B B2 upon the plate A. The upper ends of the blocks Gare slightly rounded, as at b, and the side blocks, D D2, concaved, as at c, and having their upper inner sides inclined at e. These blocks D D2 are made wider at their lower than upper portion, so that while the flanges B B2 of the plate A are received and held between the block C and the blocks D D2, the lower portions of these blocks shall have their bearing against the sides of the block C. The construction of these blocks is more particularly shown in Fig. l of the drawings.

The operation may be thus described.A The plate A is placed upon the central block, C, the anges B B2 overhanging the sides of the same. The blocks D D2 are then moved up in position until the upper inclined portions bear against the iianges B B2, and their upper portions support outer edges of the plate A and are then tightened in the chase by the quoins, furniture, or side -sticks usually employed for the purpose, theirlowerinner sides being brought flush with the sides ofthe central block, C.

lt will be seen that by the construction of the plate A and blocks O D D2, as set forth, the plate,when placed in the chase for printing purposes, will be securely held in position and prevented from working loose.

Having now sct forth our invention, we claim as new- The combination of a plate, A, flaugcthas at B B2, with a central supporting block, O, and side locking-blocks,D D2, constructed and operating substantial] y as and for the purpose set forth.
